1. A power failure indicating system for a traffic signal head, the emergency battery backup system comprising:
a battery;
a control board operably connected to the battery;
wherein the control board includes a DC input terminal that is operably connected to the battery for receiving DC power from the battery, and a DC output terminal that is operably connected to a red light of the traffic signal;
wherein the control board includes AC input terminals for receiving AC power, and AC output terminals that are operably connected to the red light, and to a yellow light and a green light of the traffic signal;
wherein the control board directs DC power from the DC input in the event of a loss of AC power, so that the red LED goes into a flash mode to alert drivers that the traffic signal head is out.
